Note: because safety standards maintain that you need a maximum space of 120mm between burglar bars, it's always safest to round UP. Sometimes, however, this may not be practical - consult us via telephone or e-mail if you are unsure.

InvisiBars™ DIY are sold in 3m strips. To avoid wastage, send us your cut list (or measurements) and we'll determine how many bars you can cut from each 3m strip.
